Numberama 2 is coming! Rediscover the classic number puzzle that kept students hooked in the 80s and 90s — now rebuilt as a smooth, modern time-killer for iPhone and iPad. How to play Start a new game and you’ll see numbers from 1 to 19 (no zeros). Your goal is to clear the entire board by crossing out pairs of digits: Same numbers (e.g., 7 + 7) Numbers that add up to 10 (e.g., 9 + 1) Pairs can be crossed out when they are next to each other (horizontally or vertically), or in the same row/column with only empty spaces between them. Rewrite rule (important!) After you remove pairs, tap Rewrite to rebuild the remaining numbers into new lines. Sometimes certain digits (for example 9s) may not appear again after a rewrite — that’s not a bug. It’s part of the original rules and a key element of strategy: plan your moves to win. Features • Classic mode with numbers 1–19 (no zeros) • Random mode for advanced players • Fun achievements • Up to 20 undo steps — recover from mistakes anytime • Undo with a simple swipe • Detailed stats: score, time, lines, pairs, remaining pairs • Separate high scores for Classic and Random • Save your results to Photos / Camera Roll • Demo mode for training • Optimized for iPhone & iPad (Retina) • Game Center support

Two fleets face each other across a star map that does not exist yet. You build it, one tile at a time, as you explore. A turn-based board game duel, played solo against the AI or with a friend across phone, tablet and PC. A game lasts about twenty minutes. HOW YOU WIN First to conquer five planets in ten turns takes it. Lose every planet you hold and the game ends there. EVERY TURN, FOUR DECISIONS • Explore — place a tile and open a new stretch of the Celestial Vault • Harvest — collect Star Pepper and Celestial Vanilla from the trading posts you hold • Manoeuvre — move your galleon and frigates, spend your crew cards • Build — buy frigates, raise fortresses, pay a planet's price THREE NATIONS, THREE WAYS TO PLAY The British Royal Navy, the French Royal Navy or the Spanish Armada. Each fields its own captains and its own crew: the Spanish Governor talks a planet's price down, the French Lady of the Night fills your holds, the Gunner opens fire. You pick two captains and five crew members before the first tile is laid. That choice shapes the whole game. NOTHING IS FREE Your holds never exceed five spices. Firing costs a Gunner card. Your captain's ability only triggers if a Chief mate is there to relay the order — and if your galleon falls, your captain goes down with it. SOLO OR TWO PLAYERS • Solo — face an AI that drafts its hand, plays its cards and races you to the fifth planet • Duel — play a friend across Android, iOS and PC HAND-DRAWN CELESTIAL CHARTS Engraved constellations, gilded compass roses and inked portraits: Efemeris is played on an old star atlas that slowly fills with light. A complete game. No ads, no in-app purchases. Available in English and French.
